The inversion ankle sprain is the more common of the two types of injuries.

The ankle area has three sections — lateral, medial, and high. All three areas of the ankle are prone to painful sprains.

Lateral ankle sprains — the most common type — injure the ligaments that prevent your foot from rolling inward toward the arch.

Medial ankle sprains cause damage to the set of ligaments that keep your foot from rolling outward.

High ankle sprains — sometimes called "tib/fib" sprains — injure the ligaments that hold your two leg bones together on top of the ankle. A forceful, upward movement of the foot and ankle causes this type of ankle sprain.

Ankle sprain causes and risk factors

Ankle sprains can occur for many reasons.

Some common causes of ankle sprains include:

Wearing the wrong type of shoes for your sport. This puts you at risk of twisting your ankle or even falling.

Placing unusual stress to the ligament. This could be from walking or running on an uneven surface, jamming your foot, or twisting your ankle in an odd way.

High impact sports — where you run, jump, climb, or kick — can put you at risk for an ankle sprain.

Ankle sprain complications

Without proper diagnosis, treatment, and care, an ankle sprain can impede your ability to walk and do other routine activities.

A sprained ankle might make you walk unevenly. This causes you to put more weight on the healthy ankle and increases your risk of injuring that ankle.
